Plastic Solenoid Valves

Plastic Solenoid Valves provide 2-way on-off control for water, inert liquids, and other compatible low-viscosity media where corrosion resistance, lighter weight, and non- metallic body construction are preferred. This valve family includes compact plastic valves for smaller tubing and water treatment systems, while it also includes larger semi-direct acting plastic valves for utility water and general fluid handling applications.

 

Available configurations include direct-acting and semi-direct acting designs, normally closed and normally open options depending on series, female NPT and quick-connect connections, and sizes from 1/8 inch to 2 inches. As a result, these valves fit low-pressure systems where body material, seal material, and dimensional fit must match the application.

Available Configurations

  • Valve type: 2-way direct-acting or semi-direct acting, depending on series
  • Body materials: Polypropylene plastic, POM plastic, Engineered Nylon Plastic (PA66)
  • Fail Safe Position: Normally closed (NC), normally open (NO), depending on the series
  • Connection type: Female NPT, quick connect
  • Seal material: EPDM, EPDM diaphragm
  • Mounting: Vertical or horizontal
  • Coil voltages: 12V DC, 24V DC, 24V AC, 110V AC, 220V AC, depending on series and size
  • Duty cycle: 100% continuous duty
  • Protection class: IP54 on RSC series, NEMA 4 / IP65 on PSL series
  • Available sizes: 1/8 inch to 2 inches, depending on the series

Technical Specifications

Plastic Solenoid Valves in this family are used where corrosion resistance, compact construction, or non-metallic wetted bodies are needed for water and compatible fluid service. However, exact values vary by series, size, valve action, and coil selection, so buyers should confirm final selection against the applicable spec sheet.

Pressure, Temperature, and Media Fit

These valves are designed for low-pressure water and compatible fluid systems where plastic construction is preferred. For example, the RSC threaded model uses a direct-acting design and can operate from 0 psi differential pressure. In contrast, the RSC push-in model uses a semi-direct acting design and requires a minimum of 3 psi differential pressure for reliable operation. The PSL series is a semi-direct acting plastic valve that is gravity feed capable and operates from 0 psi minimum pressure.

Media compatibility varies by construction. For example, the RSC series is positioned for clean water and low-viscosity fluids, while the PSL series is suited for inert liquids and gases, water, and other neutral media. Therefore, review the final seal and body selection for chemical compatibility.

Dimensions and Size Range

Dimensional fit varies by series, size, and valve action, so buyers should review the applicable dimensional data before specifying for equipment layouts, pipe clearance, or compact assemblies. Specifically, RSC plastic models cover 1/8 inch and 1/4 inch sizes, while PSL plastic models cover 1/2 inch to 2 inch sizes in normally closed and normally open configurations.

Series Body Material Size Range Notes
RSC Threaded Polypropylene plastic 1/8 inch to 1/4 inch Direct-acting female NPT design
RSC Push-in POM plastic 1/4 inch Semi-direct acting quick connect design
PSL Series Engineered Nylon Plastic (PA66) 1/2 inch to 2 inch Semi-direct acting female NPT design, available in NC and NO

Design and Performance

  • Plastic body construction for lightweight, corrosion-resistant installations
  • Direct-acting and semi-direct acting options depending on the series
  • Compact small-port models for tubing and water treatment systems
  • Larger port semi-direct acting models for utility water and general flow control
  • Low-pressure operation, including zero differential pressure capability on selected models
  • Suitable for continuous energization, 100% duty cycle
  • Can be mounted vertically or horizontally

Series Options

RSC Plastic Series

The RSC Series covers compact plastic body valves used primarily for clean water and low-viscosity fluid service. The threaded model uses a direct-acting design with 0 psi minimum differential pressure, while the push-in model uses a semi-direct acting design and requires 3 psi minimum differential pressure.

In addition, this series includes polypropylene and POM body constructions, EPDM sealing materials, and female NPT or quick-connect port options.

PSL Plastic Series

The PSL Series is a larger semi-direct acting plastic solenoid valve for inert liquids and gases in 1/2 inch to 2-inch female NPT sizes. It uses engineered nylon plastic (PA66) body construction and EPDM diaphragm sealing, while it is available in normally closed and normally open configurations. As a result, this series suits low-pressure utility water and general fluid control where larger port sizes are needed.

Typical Uses

  • Humidification and misting systems
  • Water treatment and filtration equipment
  • Ice production equipment
  • Drinking water dispensers and fountains
  • Aquaculture and aquarium systems
  • Commercial dishwashing equipment
  • Beverage processing and dispensing systems
  • Industrial cleaning and washdown systems
  • Hydroponic cultivation systems
  • General water utility control
  • Water sprinkler systems, non-fire protection
  • Process water distribution and dosing systems

Technical Resources

For exact dimensional, pressure, and electrical values by size and configuration, review the applicable series documentation before ordering or quoting.

Technical Note

These valves are not intended for use in medical life support, combustion, aviation, aerospace, automotive, or similar applications. In addition, some compact plastic valves may be unsuitable for gravity-fed systems due to a small orifice size. Review final material and seal selection for chemical compatibility.

Flow Diagram Instructions:

  1. Loosen and remove the Phillips-head screw securing the DIN connector to the coil.
  2. Detach the DIN connector from the coil.
  3. Open the DIN connector housing by prying at the small slot located in the bottom corner next to the Earth terminal.
  4. Inside the housing, locate the screw terminals:
    • Terminal 1: Connect the hot or positive wire.
    • Terminal 2: Connect the neutral or negative wire.
    • Earth Terminal (for AC voltages only):  Connect the hot or positive wire.
  5. Ensure all screw terminals are securely tightened for a reliable connection.
  6. Reassemble the DIN connector by reversing the steps above.
